An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-26163 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-26163/ (Markdown: https://insights.sbomify.com/CVE-2020-26163/index.md)","id":"CVE-2020-26163","markdown":"https://insights.sbomify.com/CVE-2020-26163/index.md","name":"CVE-2020-26163","record":{"aliases":["GHSA-5wp7-85p7-qq6v"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Greenlight web app","requires_auth":"none","summary":"Attackers can hijack accounts via spoofed password-reset links exploiting Host and Origin header manipulation in Greenlight.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"greenlight","vendor":"bigbluebutton"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"BigBlueButton Greenlight before 2.5.6 allows HTTP header (Host and Origin) attacks, which can result in Account Takeover if a victim follows a spoofed password-reset link.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Open redirect in n/a","id":"CVE-2020-26163","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2020-26164"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-26162"},"products":["n/a"],"published":"2020-09-30","related":[{"cvss_score":9.1,"headline":"BigBlueButton Greenlight Open Redirect vulnerability","id":"CVE-2022-36028","kev_date_added":null,"published":"2024-04-25"},{"cvss_score":9.1,"headline":"BigBlueButton Greenlight Open Redirect vulnerability","id":"CVE-2022-36029","kev_date_added":null,"published":"2024-04-25"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2020-27642","kev_date_added":null,"published":"2020-10-22"},{"cvss_score":5.4,"headline":"Cross-site scripting in n/a","id":"CVE-2022-26497","kev_date_added":null,"published":"2022-06-02"},{"cvss_score":4.3,"headline":"Improper privilege management - Anyone can view room settings in GreenLight","id":"CVE-2022-31039","kev_date_added":null,"published":"2022-06-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can hijack accounts via spoofed password-reset links exploiting Host and Origin header manipulation in Greenlight.","url":"https://insights.sbomify.com/CVE-2020-26163/"}
